I finally did it. Steve Dinan's coil over suspension.

Got my m8c back from Carbahn today. The new suspension is amazing, the car feels super composed at all modes. Had to re adjust to carry more corner speed in the hills where I did the test drive (sorry Toyota drivers - I am a bit ashamed of my driving today haha). The stance is also much better now, although it should fully stabilize in a few days.

Some photos attached (renewed)

I asked for medium. But the car should get a bit lower in a few days once the coils settle.

Could you take a nice side pic to show drop. For me the drop is purely aesthetic. Think your the only m8 out there that is being built to be tracked

Is this a true Coilover system or a HAS?

If true what did you do to defeat the EDC?

Carbahm told me it’s a HAS and was reused from the f90 system. They thought it was going to be a direct fit but guess the spring rates were wrong

Also looks a bit taller in front like ours. The M5 springs are too long for the M8 I think...

Re-uploaded the photos. These are the custom springs for M8, the M5 springs Carbahn springs which was the original plan didn't fit.

Considering the lowering option. CARBAHN is local to me with Steve Dinan actually in the local shop. Pretty cool. System is 1500 and a Available unlike the KW which takes 3 weeks from Germany. They say max drop is around 1 inch. 9 hour install job for them. Seems like a long install

Nice.
Do you in any chance have picture of the product itself?

Yea, not sure with 9 hours install job.
Seems way too long for just a spring install.

That's because I have to shower and change clothes so many times since you have white interior.

Do you know about torque specs and whether they reused/replaced every bolt?
